How big is Honduras's transmission network?

OverWatts maps 882 km of transmission line in Honduras, across 31 segments, plus 0 substations. This is mapped length from OpenStreetMap, not an operator-reported total — where OSM is incomplete the figure is a floor, never a ceiling.

What voltage is Honduras's grid?

Most of the mapped network is high voltage (220–379 kV): 882 km of 882 km. The highest voltage tagged anywhere in the country is 230 kV.

How complete is the grid map for Honduras?

Partial — 7.7 km of mapped line per 1,000 km² of land, ahead of 29% of the 153 countries with any mapped grid. Coverage grades how completely OpenStreetMap has drawn the network, not how much network exists; large, sparsely-populated countries score low for geographic reasons alone.

Who operates the grid in Honduras?

ENEE, SIEPAC are tagged as operators on mapped segments. Operator tags are present on 16% of Honduras's segments, so this ranks who is *recorded*, not market share.

What interconnectors connect Honduras to its neighbours?

900 MW of cross-border transfer capacity to Guatemala, El Salvador, Nicaragua, plus 900 MW planned. Capacities are from the Global Transmission Database (v1.0, 2023).

Honduras power grid

OverWatts maps 882 km of Honduras's electricity transmission network across 31 line segments and 0 substations, the 113th most-mapped grid of 153 countries. Its backbone is high voltage (220–379 kV), carrying 882 km — 100% of the mapped length, with the highest tagged voltage at 230 kV. That works out to 7.7 km per 1,000 km² of land — partial OpenStreetMap coverage, ahead of 29% of mapped countries. It is connected to 3 neighbouring grids by 900 MW of existing cross-border transfer capacity, with a further 900 MW planned.

This grades how completely OpenStreetMap has drawn Honduras's network — not how much network exists. Large, sparsely-populated countries score low for geographic reasons alone, and every kilometre here is mapped length, so the totals are a floor rather than an operator-reported figure. 3% of segments carry a real line name and 16% an operator tag.

Where there is room to connect a new load depends on published hosting capacity, which most operators release only as their own map. OverWatts does not yet ingest those feeds, so these are the density measures the open data supports — generation and mapped demand against mapped network — not a headroom figure.
